beorn7 f193f2b8ef Add a command to promtool that dumps metadata of heads.db ... I needed this today for debugging. It can certainly be improved, but it's already quite helpful. I refactored the reading of heads.db files out of persistence, which is an improvement, too. I made minor changes to the cli package to allow outputting via the io.Writer interface.		2016-03-07 16:21:57 +01:00
